"She did it again, and this time it was a gift for all of us who live near Etna - it was dinner time on a Saturday night, visibility was relatively good (except for clouds drifting across Etna's summit most of the time), it was incredibly powerful and one of the tallest lava fountains we've seen among the many dozens of similar events in the past 15 years. I'd give it a good 800 m height above the crater (of course, again the New Southeast Crater, which already had made four paroxysms during the past five days). At the end, it got really loud, and then, in a matter of a couple of minutes, the whole huge fountain disappeared altogether, and the latest episode of lava fountaining at Etna's New Southeast Crater was history.

Here's the view from near the little village of Pisano, not far from Zafferana and Santa Venerina, on the southeast flank of Etna, during the climax of the paroxysm at about 18:45 h GMT (=local time -1). Note how the fountain is absolutely vertical for much of its height, in spite of a strong wind blowing, which bent the top of the fountain northeastward and carried all the loose material, ash and scoriae, into that direction. For some time the immense jet of gas and molten rock was even inclined AGAINST the wind.

Anyone doubt that this is absolutely the most awesome, beautiful and marvellous volcano on this planet? " [link to www.flickr.com]

ok I'm back home and going through my photos and video ... The fountain was brief like nearly all events of this kind, and ended rather abruptly, in like 2 minutes from intense fountaining to almost zero, which is something quite common (there are also descriptions of the same happening during Kilauea's 1959 Kilauea Iki eruption). Very loud noise at the end, almost the best part of it. It was quite tall, I'd say up to 800 m or so, which we haven't seen during the previous four paroxysms. It even shot up obliquely AGAINST the very strong wind. Tells you something about the energy that is released in such an event. Much less lava this time. Some photos and video will be up later this evening ... [link to www.wired.com]

it means we made correct estimate!

tremor was i guess (approximately) in 2-2.5 times bigger then in four previous paroxysms: [link to www.ct.ingv.it] so i guess lava fountains could reach also bigger heights

Seismic tremor levels near Pu`u `O`o remained low. The most recent (preliminary) sulfur dioxide emission rate measurement was 300 tonnes/day on February 21, 2013, from all east rift zone sources; these values have typically been between 200 and 300 t/d from November through January and 300-400 t/d so far in February. Outside the crater and across the northeast flank of Pu`u `O`o cone, multiple lava flow lobes, informally called the Kahauale`a flow, continued to be active on the northeast flank of Pu`u `O`o and on older flows north of Pu`u Kahauale`a to the base of the 2007 perched channel (visible in Pu`u `O`o East Thermal and North Webcams); at the base of the perched channel, the flow front split with the strongest activity going to the northeast and a small amount of lava going to the southwest.

Re: The monsters wakes up ! Katla Hekla Iceland Dead Zone and rift as uniform system ! A lot of others worldwide !

An excellent story of how and why during the eruptions of lava fountains formed

[link to www.wired.com] Boris Behncke 3 days ago...these episodes are the result of the periodic foaming of magma in the conduit, even if not much new magma is furnished from depth. It's the gas that does the trick mostly. Gas is originally dissolved in the magma (like carbon dioxide in a bottle of sparkling water, as long as it's under pressure you don't see it because it is actually *part* of the water), and as the magma rises, the gas decompresses and separates from the molten rock, forming bubbles. These bubbles tend to rise faster than the surrounding magma and accumulate in the upper part of the magma column, which is capped by more viscous, cooler or even solid magma, so much of the gas don't escape. Instead, the bubbles become more and more and coalesce, requiring more and more space, and the result is that a sort of magma "foam" forms, which then rapidly expands, letting the gas and a minor fraction of magma escape. And that's what makes a lava fountain. The magma foam comes out as scoriae (or, in more silica-rich, highly explosive eruptions, as pumice), but its proportion relative to the gas escaping simultaneously is vanishingly small. So if you think of those impressive fountains of liquid lava and towering columns of dark ash, consider what immense quantities of gas (foremost, water vapor, and then also some good quantities of carbon dioxide and sulfur dioxide) are released in such events!

Re: The monsters wakes up ! Katla Hekla Iceland Dead Zone and rift as uniform system ! A lot of others worldwide !

Thus, now happens already fifth eruption for 4 days.Possible , we are moving to the level of Etna activity similar on 2000 year , wich accounts, as i remember, 66 eruptions.

Quoting: Anonymous Coward 35019861

This is not quite correct info, and here is a comparison of the current activity of Etna with 2000 year made by expert

[link to www.wired.com] Boris Behncke Holger_Alberta • 3 days agoThis is not the first time that Etna is in such a frenzy. In the year 2000, the "big brother" of the New Southeast Crater, then a healthy youngster (I'm speaking of the old Southeast Crater), awoke after a few months of quiescence on 26 January and made its first paroxysm in a series that would eventually count 66 (sixty-six) events by late-August. At first, the paroxysms came at intervals of a couple days: 26 January, 29 January, 1 February ... and then the thing accelerated in a bewildering manner. By the end of February 2000 the count stood at 38, some days had seen up to three paroxysms. So indeed, what is going on now is not all that exceptional.

One difference, though, there is. The lava fountains (paroxysms) of 2000 rarely lasted longer than 10-15 minutes each time. Those of 2011-2012 and again now each last some 45-60 minutes, so they are indeed bigger. This is quite evident from the fact that the cone of the New Southeast Crater has grown faster than its "big brother", and it seems it is vigorously growing again with the new paroxysms.

on second thought though, looking at GE, it seems there is an estuary there, so maybe a glacier flood off the big glacier is going on?

Quoting: Anonymous Coward 35001787

I think both explanations well, but as yet there are no additional data is difficult to give preference to any of them. purely speculative - I would have preferred the first explanation, that is, an underwater eruption.Why?

First, a very pretty spot, and much like the what we have seen for a long time near El Hierro

Secondly, I think that we are not seeing enough volcanic activity under the glacier in the surrounding areas (tremor, and so on),so you can expect the melting of large volumes.

Third, all known volcanoes there are far enough away from the source of stain, and in addition, well-defined estuaries to collect such large amounts of melted water I do not see.

Well, except that there is some new crack was formed?

so while I would consider rather the first option (unless, of course, rule out any industrial discharges?)

brucestout Boris Behncke • 6 hours ago.....or perhaps to phrase the question more simply: is the gas content of the magma entering the system more or less constant or does it vary? And does this variation explain the different phases or, conversely, are the phases merely a variation due to the eruption dynamics (foaming/degassing -> effusive activity).

New Zealand’s White Island volcano stirs, sends out ash clouds

Posted on February 24, 2013by The Extinction Protocol

February 24, 2013 – NEW ZEALAND — White Island is stirring again but volcanologists say activity within the crater is only minor. GNS has monitoring cameras in place at the volcano which take photos of the crater every 15 minutes and scientists noticed an increased level of activity between 11.30am and 1.30pm today. Duty volcanologist Arthur Jolly said the ash was confined to within the crater and would not affect aviation in the area. He was unsure as to what the rest of the weekend had to hold. “In certain volcanic systems you can see an evolution in the pattern and we know from many volcanoes worldwide that some volcanoes follow a pattern that leads to an eruption,” Jolly said. “But in this case, this volcano doesn’t follow this kind of set script.” By the end of last month the hot crater lake on White Island completely dried up as explosive rocks, mud and gas were thrown into the air from the active volcano. The volcano has been spewing a steady stream of gas since activity heated up in December. It’s the most active the volcano has been since 2000. –Stuff [link to theextinctionprotocol.wordpress.com]
